Which of the following is NOT one of the seven basic principles for descending a vertical face?

The primary focus when descending a vertical face involves techniques that enhance safety, control, and stability. The principle of keeping your feet shoulder-width apart is an essential practice in various climbing and rappelling situations, but it is not explicitly one of the seven basic principles outlined for descending a vertical face.

Maintaining body weight above the center of gravity is crucial for balance and stability during the descent, as it helps prevent falling or losing control. Similarly, controlling descent speed is vital to ensure a safe and manageable descent, allowing the individual to react to unexpected changes in terrain or conditions. Positioning the rope diagonally can also help manage the load and create a safer angle for descent, facilitating better control.

Therefore, while the concept of foot placement is important in climbing practices, the specific guidelines for descending a vertical face emphasize other critical principles that directly impact safety and efficiency in that scenario. In this context, the choice of keeping feet shoulder-width apart is not one of the foundational seven principles, highlighting its distinction in this specialized area of rope rescue operations.
